voured with a fpecimen of this fiiell from Mr. Boys, \vith 

 reference to the figure in Tejla minuta rariora: have 

 fince found it on the coaft of South Devon fparingly ; and 

 have received it from Mr. Brver of Weymouth, as a fhell 

 of that fliorc. 



It has generally five or fix volutions, and the ribs are 

 about fifteen m number, placed nearer together, and the 

 fiiell rather more flender than the T.Clathrus, of the fame 

 fize : there is, however, fo much fimilitude, that doubts 

 muft be entertained whether they are really diftinft, efpe- 

 cially as the number of ribs in that fiiel! is apt to vary; 

 nor does there appear any eflTentia! difference in the aper- 

 ture, although Mr. Walker calls it oval.
